Application filed November 18, 1819. Serial No. 387,777.

' like "to serve as a mounting for a bracket adapted to carry a table, tray, writing desk, book rest or the equivalent thereof, under such conditions as to permit of movmg sald tray or rest or other object carried by the bracket over the bed within convenient reach of the occupant thereof or] to be moved to one side out of the way when not in use; and to this end the invention consists in a construction, combination and arrangement of parts of which a preferred embodiment is shown in the accompanying drawing, wherein;

Figure 1 is a slde vlew of the device.

Fig. 2 is a plan view of the same.

Fig. 3 is a perspective view of one member of the clamping sleeve.

Fig. 4 is a detail sectional view showmg the mounting of the tray on the arm of the bracket under such conditions as to permit of rotating the former independently of the bracket arm.

It is desired in connection with devices of this class to provide means for mounting a bracket arm such as that indicated at 10, upon a bedpost or other upright 11 under such conditions as to securely maintain the bracket in position without necessitating any modification in or any marring or mutilation of said post, and to this end there is employed a clamp indicated at 12 consisting of the detachable members 13 and 1 each of which is of substantially semicylindrical cross section having an interlocking joint at 15, preferably formed 1n a thickened or reinforced portion 16 of the clamp members, one of said members carrying a thumb screw 17 for terminal engagement with the poster uprlght 11, and

the other being provided with a bearing eye 18 for the reception of the pintle 19 of said bracket element and from which the latter 1s disengageable to dismount the arm.

In applymgt e clam sleeve to the post or upright 11 1t 1s simp y necessary to apply the separable members'13 and 14 thereof to opposite s des of the said upright or post, WhlCh obvlously may be of an preferred cross sectional contour and imen slons, and slide one of tudlnally relative to the other to cause the engagement of the tongues 13' of one memher with the notches or recesses 14 of the other member, and the tongues 14: of the last-named member with the notches or seats 13 of the first-named member to prov1de an interlock which, when the thumb screw or set screw 17 is tightened serves to engagement with the uprlght or post against displacement either transversely or longitudinally thereof.

As W111 be understood the bracket arm is capable of a swinging movement to present its inner or free object in connection with which the bracket is used, or to be swung to an out-of-the- Way position at one side of the bed or otherstructure, and in order to adapt the same the members longiend over the bed or other to hold objects such as a tray 20 or its indicated, the bracket may be dismounted from the bearing eye 18 and remounted from time to time as may be required.

Moreover the engagement of the clamp with the upright or post is such that its removal will relieve the latter in call the same condition as before 1t was app ied, owing to the fact that the engagement thereof with the upright is through fricti l 0; bearing contact, and therefore practithe marring or mutilation of the same or any surface finish with which it'may be provided is not marred or mutilated.

What is claimed is: A device for the purpose describedhaving a clamp for engagemen with a post or upright and provided with a set screw for securing the clamp in position thereon, an

arm pivotal'ly mounted for swinging movement upon the clamp and provided at its free end with a seat, and a spider having a hub revolubly mounted in said seat and provided with a socket for the reception of a depending stud on a tray or similar object resting thereon.

In testimony whereof he afiixes his signature.
